Mark Brown	fbc2dae854	ASoC: Support GPIO based microphone detection for WM8904 ... The WM8904 allows microphone detection signals to be brought out as alternate functions of the GPIO signals which can be detected using interrupt inputs on the CPU. Allow this to be configured using platform data. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@slimlogic.co.uk>	2010-03-16 16:03:30 +00:00
